Sodium hypochlorite

Sodium Hypochlorite (NaOCl) is a chemical compound commonly used as a disinfectant, bleaching agent, and cleaning solution. In dentistry, it is primarily used in root canal treatment for irrigating and disinfecting root canals, as it dissolves organic tissue and kills bacteria.

Key Points:

• Appearance: Pale greenish-yellow liquid with a chlorine-like smell.

• Common Uses:

  1. Household bleach (for cleaning, whitening).

  2. Water disinfection.

  3. Root canal irrigation in dentistry.

• Dental Concentration: Usually 0.5%–5.25%.

• Advantages: Strong antibacterial and tissue-dissolving action.

• Precautions: Can cause irritation or chemical burns; must be handled carefully.
